Ptolemy. La geografia di Claudio Tolomeo Alessandrino. Venice, 1561.
Claudius Ptolemaeus (AD 90 – c. 168) an astronomer and mathematician living in Alexandria, Egypt, summed up the geography of the known world -- essentially the Roman Empire -- in the second century A.D. He systematically listed the latitudes and longitudes of some 8,000 places in Europe, Africa, and Asia, and described methods of projection for drawing maps. Ptolemy’s work represented a major advance in the science of mapmaking and, despite its errors, retained its authority for almost 1,400 years. It survived for centuries through manuscript copying and was put into print in 1482, all the while expanding as geographical knowledge increased. Italian Alchemist, physican and cartographer Girolamo Ruscelli (c1504-1566) issued revised and expanded editions of Ptolemy’s Geography. The present edition is the first to include Ruscelli's own maps.
